The genus Phanuromyia in the subfamily Telenominae (Hymenoptera Scelionidae) consists of 60 described species, for which host records indicate they are egg parasitoids of lanternflies and planthoppers (Hemiptera Auchenorrhyncha). In this study, we describe a new species of the genus, P. ricaniae sp. n., reared from the eggs of a planthopper, Ricania shantungensis Chou Lu (Hemiptera Ricaniidae). https://www.selleckchem.com/products/az628.html This planthopper has been considered as a serious invasive pest in South Korean agriculture. Ricania shantungensis has a wide host range, including economically important crops such as apple, peach, and pear. Phanuromyia ricaniae therefore has the potential to be a biological control agent against ricaniid planthoppers.Difflugia australis, first described by Playfair (1918), has a unique morphotype. However, in the absence of morphometric data, it has not yet been reliably classified within the largest testate amoeba genus Difflugia. In this study D. australis collected from a subtropical reservoir in southeast China was investigated by means of light and scanning electron microscopy. Basing on biometrical data, we provide an improved diagnosis of this little known species. Difflugia australis is different from other similar congeners (i.e., D. bacillariarum Perty, 1849 and D. elegans Penard, 1890) mainly by the combination of the following features the shell is broadly ovate, with rounded dome and convex sides converging down to a very short distance from the aperture and diverging suddenly into a short rim (collar). It is usually more or less asymmetrical, with one side being more dilated than the other. The shell surface is slightly smooth, composed of flat siliceous plates of irregular shape and size, mixed with fine grains; microbial spores of comparable forms are spread on the shell surface; particles are often interspersed with a network of organic cement with unique mesh pattern; one (sometimes two) slanting spine-like posterior end of the shell is variable in form; collar is mainly formed by small plates of equal size. The dimensions of the shell are total shell length 88-106 ?m; shell width 53-88 ?m; aperture diameter 19-28 ?m; collar height 3-6 ?m; spine length 3?23 μm. The size frequency distributions of both total shell length and shell width indicate that it is a size-monomorphic species with low variability.The genus Corynoneura Winnertz, 1846 from Zhejiang Province in Oriental China is reviewed. Corynoneura aggeris Fu, sp. n., Corynoneura lateralis Fu, sp. n., Corynoneura petitspectabilis Fu, sp. n., Corynoneura prolata Fu, sp. n., and Corynoneura recta Fu, sp. n. are described and illustrated based on adult males. Corynoneura lobata Edwards, 1924 and Corynoneura tokarapequea Sasa et Suzuki, 1995 are redescribed and illustrated based on newly collected material. A key to known adult males of Corynoneura from Zhejiang Province is given.An annotated list of Iranian digger wasps of the genus Tachysphex Kohl, 1883 (Hymenoptera, Apoidea, Crabronidae) is presented based on the material collected in the southern part of the country and on data published from the period 1933-March 2020 (87 years). In all, 46 species of eight species-groups are documented (T. persa has two subspecies T. persa persa Gussakovskij, 1933 and T. persa nigripes Pulawski, 1967). Of the eight species-groups, the pompiliformis species-group (17 species) and the panzer species-group (11 species) are the most species-rich, whereas the brevipennis species-group is represented by only one species. The following three species are newly recorded from Iran, all from Fars Province T. helveticus Kohl, 1885, T. melas Kohl, 1898 and T. palopterus (Dahlbom, 1845). About 19 (41.30%) of the species included here are exclusively Palaearctic, whereas 15 species (32.61%) have wider distributions in the Afrotropical, Palaearctic and Oriental zoogeographic regions. Neighboring countries have many species that overlap with the Iranian Tachysphex fauna; Iran shares 36 species (78.20%) with Turkey, 28 species (60.86%) with Turkmenistan and 18 species (39.13%) with United Arab Emirates.The maculosa species-group of the genus Promalactis Meyrick, 1908 is proposed based on the features of the forewing pattern. Members of this group have a white speckle in the forewing cell and usually with more than eight white markings distributed mostly at or above the fold and along the dorsal margin. Eighteen new species are described P. coloristigmosa sp. nov., P. cruciata sp. nov., P. lateridentalis sp. nov., P. latispinata sp. nov., P. lonchodes sp. nov., P. magnispina sp. nov., P. plicata sp. nov., P. bomiensis sp. nov., P. fasciserrata sp. nov., P. brevipalpa sp. nov., P. libona sp. nov., P. medilargissima sp. nov., P. ramivalvata sp. nov., P. aculeiformis sp. nov., P. apicitriangula sp. nov., P. curvispinosa sp. nov., P. medimacularis sp. nov., and P. serraticostalis sp. nov. Photographs of adults and genitalia of the new species are provided. A total of 50 species of the maculosa species-group are listed, including 32 previously known species.Nudibranchs in the family Discodorididae are generally medium (~30mm) to large ( 50mm) in size, sometimes cryptic, and are found in almost every marine ecosystem around the world. The diversity and systematics of the genera within Discodorididae are poorly understood and have led to numerous taxonomic changes. Hoplodoris Bergh, 1880 has recently been considered a synonym of Asteronotus Ehrenberg, 1831; however, morphological and molecular phylogenetic analyses reveal a distinct separation between these two genera. Here we provide a re-description of the type species Hoplodoris desmoparypha as well as descriptions of four undescribed species of Asteronotus and Hoplodoris. Bayesian inference and maximum likelihood analyses of two mitochondrial and two nuclear genes were used to evaluate the phylogenetic positions of the new species and clarify the relationships between Asteronotus and Hoplodoris to the rest of the Discodorididae. Based on our results, Hoplodoris is removed from synonymy with Asteronotus. Descriptions for Asteronotus markaensis sp. nov., and Asteronotus namuro sp. nov. from the Red Sea, as well as Hoplodoris balbon sp. nov. and Hoplodoris rosans sp. nov. from the western Pacific are provided.
